Customer said drive was flashing RDY.
Flashing display normally indicated current limit mode. However, if this is occurring in the ready mode, it is likely due to incorrect motor parameter settings.
Specifically, it could be that the COS (motor power factor) is set to 1.
Check the +10 and +24 VDC power supplies. It could be that they are being pulled down.
